OUTSOLE TRIMMING AND CHANNELING MACHINE.`

Application led August 1, 1913.

To atl 'Lo/0m it may concern i "le it known that I, FELIX E. VALois, acitizen of the United States, residing at Haverhill, county of Essex,State of Massachusetts, have invented a certain ne and usefulImprovement in Outsole Trimming and Channeling Machines, of which thefollowing is a specification, reference being had therein to theaccompanying drawings.

My invention relates to that class of machines which are employed inboot and slice factories to trim olf the protruding edge of the outsoleof a boot or shoe while on the last, and to cut the groove or channel inwhich the stitching is laid. The machine is employed in the manufactureof welt shoes and is of the type ordinarily known as a rough rounder andchanneler but the devices hereinafter' described improve the operationof theinachine to such an extent Ithat a relatively smooth edge is pro`duced and therefore the machine is not properly termed. a rough rounder.

Herctofore, in machines of this class so far as known to me it has beencustomary to employ an automatic feed mechanism by which the work isadvanced at a predetermined rate of speed to the trimming and channelingknives. The `speed of the feed depends solely on the speed at which themachine is run and the operator has no control over it except bychanging the speed of rotation of the machine. It results therefore thatthe mach-ine is speeded to feed the shoeforwardat a rate which willenable a poor or slow workman to use it and a rapid andskilled workmancan do no more work on it than a slow workman. In the machine embodyingmy invention no feeding means is employed, and the operator feeds theshoe through the machine by hand, 'at whatever speed he findsconvenient. It therefore results that the machine is adapted for use byboth rapid and slow workmen without any change or modificationand;inpractice it is found possible to run the machine at a speed far inexcess of that of any `(rt-her machine of this type, so far as known tome. `lt is also particularly adapted to difficult work`r because theworkman may feed the shoe as slowly as is neces Specification of LettersPatent.

controlV of the operator, but without requiring special attention orcare on his part. No adjustment is required for different sizes ofslices, except that the position of the socalledlinger grips on theflexible connection will ordinarily be varied according to the differentsizes of shoes.

The machine automatically forms an edge having anamount of Baltimorewhich is proportioned to the length of the edge to which `it is applied.i

The mechanism described herein by means of which the production of theBaltimore edge is controlled by the operator is believed to be whollynovel, andto be applicable to various `kinds of machines, such forinstance as outsole sewing machines for guiding the workinginstrumentalities thereof.` Therefore in the succeeding claims I haveclaimed it broadly and independently of ther working `instrumentalitiesof the outsole trimming machine shown and described herein.

During its passage through the machine vents the shoe being fed forwardso fast that the trimming knife will skip, since the feed stop and guidewill not permit the shoe to be fed farther than the end of the precedingcutinadc by the trimming knife, and therefore makes `it possible to feedthe work by hand instead of by automatic feed- ,ing mechanism, ashasheretofore ordinarily been done. Since the shoe is guided by the feedstop and guide which engages the edge ofthe sole as well as by thecrease guide which rests on the upper, no bunch or ir` regularity ismade in the sole when the operating instrumentalities pass by the seamof the tip.` T believe that the feed stop and guide is also capable ofuseful apq'ilicationy to nuichines having automatic feeds. While I havedescribed the machine embodying` my invention as constructed without anautomatic feed, I do not limit myself to this construction as anautomatic feed may be easily applied to the machine and will in no wayinterfere with the operation of the other parts of the machine. Asautomatic feeds areold and well known in the shoe machinery art, it hasnot been thought necessary to show or describe the same in detail in thepresent specification.

The trimming knife is given an exceedingly rapid reciprocation andtherefore makes a great many more cuts for a given distance thanmachines of this kind have ordinarily made and by this means the edge ofthe sole is trimmed vperfectly smooth.

In the machine shown in the drawings herein, the channel knife andhammer are withdrawn to enable the operator to insert or remove the workby the action of a pedal and the position of the channel kniferelatively to the edge of the outsole as well as the position of thetrimming knife during the operation on the shank and the produc tion ofa Scotch edge are both controlled by another pedal, but the two pedalsare not in use simultaneously, and therefore may both be convenientlyoperated by the workmans left foot.

In the drawings, Figure 1 is a side elevation of a machine embodying myinvention. Fig. 2 is a front elevation of the machine. Fig. 3 is a topplan view. Fig. -e is a side view of the crease-guide, hammer, channelknife, trimming knife, and feed stop and guide showing the relativeposition of the various parts during the operation upon a shoe. Fig. 5is a view of the working instrumentalities of the machine. In this Viewthe machine is about to begin to trim the shank of a right shoe, havingjust completed the production of the Baltimore edge. Fig. 6 is a detailof the channel knife actuating mechanism. Fig. 7 is a section on line 77 Fig. 3 looking in the direction of the arrows. Fig. 8 is a detailshowing the relations between the trimming knife and hammer. Fig. 9 is aview of 'a modification showing mechanism for moving the feed stop andguide during the trimming of the sole.

The principal working instrumentalities of the machine consist in thetrimming knife 11, which trims the edge of the sole, the channel knife12 which cuts the channel in the bottom of the shoe; the anvil 13 (seeFig. 2) against which the trimming knife operates; the hammer 14- bymeans of which .the stock is held stationary during the cutting movementof the channel knife, and the welt and sole are compressed andflattened; the feed stop and guide 15 (see Fig. 2) the functions ofwhich are hereinafter fully set forth; and the crease guide 16 by themovements of which the width of the edge of the shoe is determined.

To enable the following description to be more readily understood theoperation of the working instrumentalities 'of the ma- L11/asse chinewill be shortly outlined. The shoe is inserted between the crease guide16, the anvil 13 and the hammer 14, and then the hammer' advances andclamps and compresses or beats the sole and welt against the creaseguide. The hammer then remains stationary in this position momentarily.During this time, the channel knife 12 makes its cutting movement byswinging in a horizontal plane. At the same time, the trimming knife 11makes a cut through the edge of the sole. lVhen the hammer has movedback and released the work the operator moves it forward for a shortdistance limited by the feed stop and guide 15. The shoe rests againstthe crease guide 16 at the cutting point and the newly trimmed edgeengages the under side of the feed stop and guide 15 while the upperside of said feed stop and guide is engaged by the under edge of thetrimmings. The width of the edge is controlled by the crease guide 16which rests against the upper, therefore as the shoe is filled by thelast, the shape of the edge of the shoe is determined by the shape ofthe last. In the machines shown herein, the formation of the Baltimoreedge isalso controlled by the position of the crease guide 16. As longas the crease guide 16 remains stationary, an edge of even width z'. e.Scotch edge is formed, but if the crease guide is pushed down graduallya Baltimore edge is produced. The crease guide is moved by a treadle toproduce the Scotch edge and to produce the Baltimore edge it is moved bya train of mechanism actuated by a chain to which is attached a fingergrip or medal which is seized by the hand of the operator and heldfirmly against the bottom of the shoe so that as the shoe progressesthrough the machine, the chain or other flexible member is pulled outand the crease guide given a corresponding movement up or down as thecase may be, thereby varying,

the width of edge and forming the Balti more edge.

rllhe anvil 13 is secured to the frame A of the machine and isstationary and rigid and affords a bearing against which the trimmingknife cuts.

At B is shown the driving shaft of the machine. On the shaft B is aneccentric 17 surrounded by an eccentric strap 18. The eccentric strap 18is forked at its forward end, as is shown in Fig. 3, the two forkmembers being designated 181 and 182 respectively. y y

The hammer 1&1 is pushed forward against the work by the member 182,there being a heavy spring 19 interposed so that when the pressureexerted on the work by the hammer reaches a predetermined amount, thespring will yield and injury will not be done to the work, nor will themachine be strained; The eccentric strap actuates the trimming knife 11,being; pivotally secured to it by a pin 22 which extends through bothmembers of the work. The trimming knife 1l is secured by the bolt 20 tothe forward end of the knife bar Q1, being adjustable thereon by meansof the said bolt 20.

The knife bar 21 is not notched on the side `next the hammer, as shownat a, and the said notch is engaged by a projection Y) on the adjacentside of the hammer 14. The length of the projection b is less than thelength of the notch a, and the spring 19 which is interposed between thefork member 182 and the hammer 14: holds the ham' mer in its extremeforward position with the shoulder of the projection l against theforward end of the notch a except when the nose of the han'nner is incontact with the sole of the shoe, at which time the hammer is pushedback for al distance determined by the thickness of the stock. From thefore-` going it will be seen that the trimming knife and the hammerreciprocate together', except for the relative motion occurring just asthe trimming knife passes through the stock, during which time thchammer is stationary and clamps the stock firmly against the creaseguide 16. l

The trimming knife bar 21 carries on its underside a stud 23 for a camroll 241A. `This cam roll 2d actuates the channel knife bar holder andthe channel knife bar in the following manner: The channel. knife bar25, to which the channel knife 12 is adjustably secured by the screw 36,is mounted on. a lever .27 which for convenience l callthe channel`knife bar holder. Said channel knife bary 25 issupported on the holderby means of a horizontal pivot 2S for a purpose to be hereinafter morefully explained.

The holder 2T has an arm c extending rearwardly, which is pi'votcd at tothe frame of the machine, and on which the holder is swung by themovement of the trin'nning knife. Secured to the top of the knife barholder 27 is a plate 30, see also Fig. 7, in which is a cam groove 31.`The cam roll 524i, secured to the under side of the trimming knife barmovesfin the cam groove 31 and as the trimming knife bar 21 movesforward and back the holder 97 and consequently the channel knife bar25. is swung about the pivot 29 thereby giving' to the channel knife theproperly timed movement in a horizontal plane to cut the channel. Thecutting movement of the channel. knife l'. c. the .movement toward theright as seen` in Fig. 6, is timed to occur while the trimming knife ismaking its cut and the stock is held stationary between the nose of thehammer 14- and the crease guide 16.

The channel knife 12 is raised and lowered to vary the position of thechannel with regard to the edge of the shoe in the following manner: Aspreviously s .ated

the channel. knife bar 25 is supported in the knife bar `holder 27 onthe horizontal pivot f2.8. The groove (Z in the knife bar holder `withinwhich the channel knife bar holder received is deep enough to allow thechannel knife bar to swing in a vertical plane the requisite amount. Thedownward movement of the knife is limited by an adjustable stop whichconsists of a bolt 301 in a lug .32 on the front end of the channelknife bar holder. The lock nut` 33 serves to render permanent theadjustment of the bolt 530.1. 'lo the rear end of the channel knife bar25 is secured a link Bil which .is itself also secured lto the treadleconnection 255 operated by a `trcadle 6G which l call the controltreadle. To permit the channel knife bar `to swing the requisite amount,the rear edge of the plate 30 is cut away on the under side as shown atElli. rl"he rear end of the channel knife bar is engaged by a spring 3Twhich tends to hold thcknife bar down on the stop bolt 301., so thatwhen the parts are in their normal position c. at rest, the channelknife is in its lowest position `and which is the position which itoccupies when operating upon the shank of thc shoe where it is desirableto have thc channel cut at a distance from thc edge of the shoeto enablethe outsole sewing machine to operate successfully. .As the operatormoves the shoe through themachini and reaches the point between thc balland the shank he depresscs the treadle and this brings the channel knifebar to the edge of the shoe so that from` then on the channel is cut inproper `position around the sole of the shoe. Then the knife againreachcsthc point between the ball and the shank thctreadlc is .re-`leased so that along the shank the channel is cut at a distance from theedge of the shoe. The spring l? jjrreviously referred to also tends tohold thc channel knife bar` as far forward as possible so that the knifewill cut the channel to the full depth for which the knife set. Thedepth of the channel is varied by changing the position of the knife 12on the knife bar 25 b v means of the screw 2G. The tension on thc spring37 is adjustable by means of the adjusting screw 91 having its head onthe hack side of the machine.

To permit the hammer 14 and the channel. knife 12 to bc drawn back toallow the insertion of the work, the following 1ncchanism isprovidcd: At3S is shown a .rock shaft provided. with rearwardly extending lever 39to which is attached the treadlc crmncction -Il-O operated by a treadle67 which .may be termed the starting treadle. The rock shaft 38 isprovided with two fingers 41 and 42. lVhen the lstarting treadle ispressed down the finger 4].. en-

gages a small pin 43 ou the side of the churn;

nel lmife bar and slides the channel knife bar back on the pivot 2S,which is in a slot 44 in the channel knife bar. The channel knife bar isheld back as long as the treadle is depressed. rock shaft 38 contactswith the mushroom head of snap pin 40. The inner end of said snap pin 46at times enters a shallow groove 47 in the side of the hammer 14. Whenthe starting treadle is depressed, the finger 42 moves out of engagementwith the mushroom head 45 of the snap pin 40 so that the pin snaps intothe groove in the hammer when the hammer is next drawn back by theeccentric strap. rlhereafter and as long as the starting treadle isdepressed the ha-.nmer cannot move forward beyond a predeterminedposition because the end of the snap pin engages the rear end of thegroove 47. As soon as the starting treadle 67 is released, a spring 48restores the finger 42 to its original position and pulls out the snappin 4G so that thereafter the hammer may move forward and engage thework.

T he mechanism by which the position of the shoe relatively to that ofthe trimming knife is varied and by which the width of the edge z'. c.the Scotch edgeof Baltimore edge is produced, will now be described.

it 15 is shown a stationary member which l term for convenience the feedstop and guide. This feed stop and guide is secured to the frame of themachine and is adjustable vertically by means of the screws 49 so thatits position although normally stationary maybe changed slightly asrequired. The feed stop and guide 15, see particularly Fig. 5 has a.horizontal finger which is conveniently eval in cross section andengages the underside of the trimmings which is cut olf by the trimmingknife. It also preferably engages the trimmed edge of the shoe and islocated as close as possible to the trimming knife 11. At 16 is shownthe vertically movable crease guide, the face f of which rests againstthe upper on the last. I term this member for convenience the creaseguide but it will be understood that it may rest against the upper inwhich case it might be termed the last guide. From Figs. 2 and it willbe seen that the crease guide 16 is slotted and surrounds the anvil 13,being guided between the head of the machine, which is shown at A. and afront plate 51 secnred to the head. The crease guide 16 is normally heldin its highest position by means of a spring 52 contained in a hole inthe plate 51 and engaging a lug on the top of the crease guide` Theupward movement of the crease guide is limited by a stop bolt 54 in alug 55 on the head A of the machine, the usual locknut 56 beingprovided.'-0n the back of the crease guide 16 is a stud 57 on which is aroll 58,

rlhe other finger 42 on` the 1,11a,eee

60, the rear end Vof which passes through a hole 62 in the frame of themachine, said hole being enlarged to permit the front end of the shaft60 to be raised and lowered without binding. At 63 is shown a slide pinthe lower end of which rests on the shaft 60. The forward end of apressing lever 64 rests on the upper end of the pin 63 while the rearend of the pressing lever is pivoted at G5 to the frame of the machine.The pressing lever 64 is moved down when required by the operator bymeans of the contro-l treadle 66 and link 67. The treadle 66 is the onepreviously described which controls the vertical position of the channelknife 12. A spring G8 is interposed between the link 67 and the pressinglever 64 so that after the pressing lever has reached the limit of itsdownward movement, the treadle may continue to move the rear end of thechannel knife down.

0n the shaft 60 is located a small rimmed pulley 69 around which iswrapped a chain or other flexible connection 70. The two ends 701 and702 -of the flexible connections pass over a two-grooved pulley 71 whichis mounted on a stud 72 on a boss on the front corner of the cover 7 3which serves in part to guide the hammer 14. The two ends 701 and 702 ofthe flexible member pass through a hole 704 in the front end of thechannel knife lbar and have secured to them two finger grips or medals 75 and 76 respectively. The'finger grip 75 is marked L and the grip 76 ismarked R to indicate which grip is to be used on the right shoe andwhich on the left. lThe hole 74 in the channel knife bar 25 is of ovalcross section as is seen in Fig. 1, and is flared somewhat on the lefthand side of the channel bar, as is seen in Fig. 2. lt is also dividedby a small partition 92, said partition being located near the righthand side face of the channel knife bar. The grips or medals are eachtapered slightly as shown at g and are of such a size that they mayenter the flaring hole 74 for a. short distance. Therefore whenever theoperator draws one finger grip away from the hole 7 4 and the otherfinger grip is drawn back into the flaring hole 74, the grip 'will be invertical position with its flat face substantially parallel to the soleof the shoe and closely adjacent to it, so that the workman mayconveniently seize the finger grip with its fore finger holding thefingerl grip against the bottom of the shoe. The parts 1 Ier treadle, asfrequently happens.

' out with the shoe and the cam shaft 60 will be rotated an amountdetermined by the length of the flexible connection. The length of theflexible connection may be ad- `justed by some suitable means as forinstance by the thumb screw 93 which moves the sleeve 94 on which thetwo-grooved pulley 7l is mounted. The rotation of the cam shaft in onedirection pushes down the cam roll 58 and therefore the crease guide 16and increases the Width of the edge left on the sole by thetrimmingknife. The rotation of the camshaft 60 in the other directionallows the crease guide 1G to be raised by the spring 52 and thereforethe width of Ithe edge is progressively diminished.

f The grips `75 and 7 6 arepreferably conf cave on both` sides and arealso knurled or roughened at h. as Will be seen in FigpZ so that theoperator may hold the grip `immovably in place against the sole of theshoe.

As Will be seen from the drawings, the cam roll 58 is located beneaththecam 59 and when the pressing lever G4 :is at its lowest position thecollar 80 so stops its further movement and supports the pressure of theoperators foot in case he stands on the This arrangement is a greatadvantagebecause there can never be any undue pressure put on the camshaft 60 or intermediate parts.`

The collar 80 is adjustable vertically on the pin 63 which is screwthreaded there being a set screw 95 to hold it in place when onceadjusted. The position of this collar determines the width of the Scotchedge. .Also it starts the next shoe in the right position to begin theBaltimore edge having` finished the Baltimore edge on the precedingshoe.

At 110 is shown heating means asa gas burner by means of which thecrease guide 16 may be heated to iron the portion of the upper withwhich it contacts. Small wrinkles frequently occur at the toe andelsewhere whichmay be thus ironed out easily especially iftheshoe is notfed forward too fast or if it is drawn back and fed forward once ortwice as may be easily done since the feeding is done by hand.

The operation of my machine is as foll lows Assuming that the right shoeis the lirst one to be trimmed, the machine begins at the heel end ofthe inside of the shank, works along the shank, then along the inside ofthe ball, then around the toe along the outside of theball, and finallyalong the shank to its heel end. The machine is then in position to`begin the operation `on the left shoe. This takes place in the reverseorder. To insert the work the operator depresses the channel knife bar25 by the action of the `linger lll which engages the pin 'till Thedepression of the treadle also allows thesnap pin i6 to catch the hammerl.l on its next backward movement and prevents the hann'ner advancingwhile the` work is being put in place. The work is then inserted withthe upper at the heel end of the shank, against the crease guide 16, thewelt and sole being on the back side of the crease guide lll and theanvil 13. The starting trcadle is then released. The hammer`let-compresses the welt and sole against` the anvil. and clamps the workin stationaryV position. lVhile the shoe is stationary the channel knifemoves horizontally and makes y the firstcut of the channel which. isat adistance from the edge of the shank. At the same timethe trimming knifecuts through the edge of the sole. 'lhe next rotation of the machinewithdraws the trimming knife and the hammer so that the operator canfeed the shoe forward. `He `then moves the shoe forward for a distancedepending on his skill` and the character of the work, but which is lessthan the width of the`trim ming knife, since the feed stopyand guideprevents it being advanced farther.' This feed nlovcment which in themachine shown in the drawings is produced Wholly by hand, takes placewhile the channel knife is swinging back to its original positionpreparatory to making the next cut. After the shoe has been fed forwardthe hammer and trimming knife again ad ance and the channel knife makesthe succeeding cut, this cyele.of movement being rapidly repeated. Assoon as the first cut has been made the feed stop and guide passes intothe space between the trimmings and the edge of the sole and thereafterthefeed stop and guide plays an important part in the guiding of the fedtoo fast. The feed stop and guide and the crease form two points ofsupport `for the work, the former being stationary and the latter beingmovable. `While the feed of this shoe forward as herein described, is astep-bystep motion it is in actual operai tion apparently continuous,because the ma-y chine makes a very quick succession of move ments, andthe work is fed forwardbvhand at substantially a uniform rate. l lt maybe stopped at any` point withoutnjury tothe work and may be advancedslowly or rapidly without producing anappreciable difference in thequality of the work. When the working instrumcntalities have reached theend of the shank which isalso the beginning of the ball, the operatordepresscs the other treadle 6G, and thisraises the channel knife 1l,swinging it on thepivot 28, and brings the channel closer to `theedgeofthe sole. The depression ofthe treaclle shoe as well as by preventingit being iso l l pressed as the shoeis advancing. The op also pulls downthe presser' lever 64 and the pin 63 until the collar 80 strikes the topof the head. rlhis swings down the end of the cam shaft 60 and lowersthe crease guide against the pressure of the spring 52 for an amountdetermined by the position of the collar 80. Thereafter, as long as thelparts remain in the position described the trimming knife will severthe sole at a uniform distance from the upper and will form theso-called Scotch edge along the inside balland toe of the shoe, to thepoint where the Baltimore edge is to begin. The transition from theshank edge to the Scotch edge will be gradual because the treadle isdeerator then continues to advance the shoe,

' swinging it properly to trim the toe of the shoe and to form a Scotchedge around the toe. If no Baltimore edge is to be formed on thev shoethe treadle is held down until the beginning of the shank is reached onthe outside of the shoe when the treadle is released and the partsreturn to the shank trimmingl position as seen in Fig. 5. If a Baltimoreedge is to be formed on the shoe', thefollowing operation occurs. Assoon as the operator has turned the toe of the shoe, he seizes the medalmarker R, which is the medal then in horizontal position, with one endin the hole 74. The operator then holds the medal firmlyv against thetoe of the shoe with his forefinger as is indicated in Fig. 5, andcontinues to feed the shoe forward until the beginning of the shank isreached. The movement of the shoe from the toe to the beginning of theshank draws out the flexible connection 70, revolves the cam 59, andprogressively depresses the crease guide for an amount determined by theshape of the cam. rlhis operation continues until the end of theflexible connection is reached because the other medal has brought upagainst the socket in the channel knife bar. The operator then releasesthe treadle and the shank trimming operation takes place 4in the usualmanner, completing the operation on the right shoe.

It will be seen that when the right shoe is trimmed the parts are leftwith the cam in the position which it occupies at the end of theformation of the Baltimore edge. rlhis is the correct position to beginthe formation of the Baltimore edge on the left shoe, this shoe beingtrimmed in the reverse direction. It' will therefore be seen that themachine is particularly adapted to trim rights and lefts alternately butthat if circum# stances require a succession of rights or lefts theycan. be trimmed by pulling the proper medal out after each shoe istrimmed to restore the cam 59 to the proper starting position.

The amount of Baltimore edge given to the shoe is determined by theshape of the cam. The particular shape of the Baltimore edge is alsodetermined by the slope of the cam. If a gradual Baltimore edge is re-kquired the cam will be given a substantially uniform slope7 but it maybe given an abrupt f slope at any point where it is desired to form arelatively large Baltimore edge. The mechanism described forms theBaltimore edge in proportion to the length of the flexible connectionwhich is pulled out. Thus if the cam gives a Baltimore edge of a quarterof an inch on a shoe in which the Baltimore edge extends for a distanceof four inches along the edge of the sole, it will give a Baltimore edgeof three-quarters of a quarter inch on a shoe having a Baltimore edgeeX- tending along three vinches of the sole. By this means the amount ofthe Baltimore edge is proportioned to the length of the sole.

In Fig. 9 there is shown a modification of my invention. In this formthe feed stop and guide 111 is-vertically movable bymeans of the twotreadles 112 and 113, and the chains 114 and 115. 4 The extreme top andbottom positions areadj usted by screw stops 116 and 117, and thesprings `11S and 119` tend to hold the feed stop in its centralposition. By this arrangement the Baltimore edge may be produced Ievenif the crease guide is held stationary, since the feed stop and guidewill then be slightly higher or lower than the trimming knife and eachcut will therefore be slightly above or below the preceding cut.
